Working at Duolingo, employees have ample opportunity to improve their own foreign language skills. Besides the fact that most people in the office are multilingual and converse in various languages, the office organizes its own language tables to help people practice their speaking in whatever language they’re interested in. The group discussions are a fun way to bring co-workers together in a low-pressure environment—like going to a Brazilian restaurant together and practicing their Portuguese.

With more than 170 million users, Duolingo is the world’s most popular way to learn languages online. Duolingo is completely free for users, and the company aims to build a future where the highest-quality education is accessible to all and tailored to each student. The approach is simple but effective—utilizing technology to make language learning fun, personalized, and based on science.
